. Tea llwhom/timely concern: lie it known that-I, EDWARD T. BURRowEs, a citizenof the United States, residing at Portland;- in the countyof Cumberland and State of Maine, have invented certain new anduseful-Improvements in Metal Screen Gruides, of which the following is a specification. 1

This invention'relates to guides for use in connection. with window screens, and par-. ticularly to guides of this nature formed of metal, distinguished from wood.

The objects of the invention are to provide an elhcient and. convenient giude of this window with myimproved guides" applied tl'iereto, and showing a screen in position;

ring to the drawings in detail, they v? ndoiv traine is designated at 1,Wh1leidicate the upper and lower sashes.

:ierovad; ide preterablyjhshaped in cross section and comprises the two flanges '5 and 6. By reference tojFig, 8, it will be seen that a flat strip of sheet metal is bent longitudinally. along-the dotted line indiycated at 5" so as to form the flanges 5 and 6 at substantially rightangles to each other. The flange ,6 preferably has its end 14: pro- 'jectin'gbeyond the flange 5, and is provided with an. opening 175 wherebytheprojecting portions of two adjacent sections may be overlapped and fastened, with a nail or screw, as hereinafter more fully described.

-Referring to Figs. 1 and2, 'I have desig nated the various sections" of my improved guide by the letters A, 'B, (3,1). These sections are re different lengths, The section A, for example, may be quite sho'rt and is designed to be: placed at the upper end of the frame.

Adjacent this is; a section B, carrying a spring 10 in the manner-hereinafter described. Then comes another section such as A, without a spring, then another secr,tion such as B, carrying a spring. In the middleofitlie window adjacent the meeting rails of-thetwo sashes is arranged a section C, which is prcferablylonger than the others so as to provide a space for the insertion ofthe screen. .Below the section C are arranged two more sections B separated by a section 1 A.,.andat the bottomthe space is-filled in by a' section.D ofsuitable length. By this arrangement there is provided two "springs adjacent each sash and these'will ordinarily besufiicient. It will, of-course, be understood, however, that any desired number ofv springs may be employed separated by blank sections of any suitable length. As all of the sections are substantially similar in construction', it will be necessary to describe in v detail only-one of them. The flange -6 of.

each section will be referred to as the bottom, and this is adapted to be secured, as by nailing, directly to the stop-strip of the window frame. The other flange-5 serves as one wall of the guideway, gainst which the side ofthe screen frame bears. a I

Referring to Figs. 3 and 4, it will be seen that the-bottom of the guide has'a series of pressed-up portions 8 formed therein, which alternate 'withjzhe portions 6 which rest adapted to receive fastening devices. At one end of each section such as B,the projecting tonguel l is} raised, while at the op- Patented Aug; 531, 1915.

latively short, and are usually of against the stop-strip, and which are pro; I vi'ded with one or more perforations 7,

posite end, the corresponding tongue, such as 16, lies in its normal "plane. A tongue such as 14 is therefore adapted to overlap a tongue 16 of the adjacent section so as to bring the perforations therein into registry, and a nail 17, or the like, may then be driven through such overlapped ends into the windowframe. When thus assembled, it will be :clear from an inspection of Figs. 3 and 4, that the entire bottom of the guide is made up of a series of-alternating elevated anddepressed portions, the edge of the' screen riding upon the elevated portions. This results in'causing the screento run free 15 of any .nail heads which are located in the depressed portions, and also causes it to clear-the lapped ends of the sections. In other words, the height of the elevated portions is at least equal to the combined thickness of-the two tongues, 14 and 16, andin practice, should be still greater, so as to allow for nail heads and thelike which may slightly project. It will be understood that the ends of the flange 5 are preferably cut off. square and abut, as indicated at 18 in Fig. 4, thus forming a smooth wall, but these ends may be made to lap, if desired. In order to prevent the formation of cracks or openings between the raised portions 8 and the-window frame, I form along the edge of each such portion adjacent the flange 5, a straight rib or bead'as clearly shown at 9 in Fig. 5. This lies fiat against the window frame andinsures a tight fit, so as to exclude insects. In. order to hold the screen in the guide, I provide the springs 10 above referred to. Each ofthese springs is of bow form and is rigidly secured at one end to one of the sections B of the guide. This may be done by forming a projection on the spring, but as shown in Figs. 3 and 4, a bracket 11 is provided to which the end of the spring is riveted or otherwise secured. The'free end of the springi'which is prefers ably upturned as indicated at 10?, rests against a stop or bracket 12, which may be formed integral with or ri eted'or otherwise secured to the section B o the guide strip. It will be understood that the brackets 11 and 12 are mounted in t e depressed por-. tions of the bottom flange 13, and are spaced slightly therefrom so as to form between themselves and such flange a space reception of the screenl3'.

It Wlll be understood'th inserted adjacent the'section'Cof the guide which does not carryany spring and which is longer than the "others. When forced. down between the springs 10 and the'flange 5, the screen is frictionally gripped in such a way as-to hold it in position, and at the same time admit of its being raised and-lowered as desired. By employing an angle bar in place of the usual channel bar, Ilachieve an advantage in case of manipulation and of bar.

for the X tthe screen :is

the lower end of the window, the flange 5 of such section being extended considerably beyond the flange ('3, bent around at substan} tial right angles as indicated at 5, and thence upwardly as indicated at 5*. upper end of the strip 5' rests against and; may be secured to a lug or bracket 19 carried by the flange (3. The strip 5 and 5" thus bent forms a socket into which the lower edge-of the screen fits. such 'socket' being preferably of decreasing width toward the bottom. whereby the screen is mor'e'readily guided and may be frictionally gripped as it ap 'n-oaches closed positio na In order to positively lock'the screen in such'closed. position and prevent opening thereof by a.

person outside of the building, I may, in. some cases, provide the latch illustratedin Figs.l1 and 13. This consists. of a pin 20 adapted toenter alined openings in the flange 5 and screen. This pin is carried by a flexible strip or spring 21 riveted to the flange 5. When it is desired to raise the screen, the pin mav be withdrawn readily by'a person on the-inside, but is inaccessible to a person without. 5

What I claim is: 1. A screen guide comprising an angle 9 bar,-a pair of spaced brackets carried thereby, and a bow spring spcured at one end to one of said brackets and engaging the/other bracket at its free end, the middle portion of the spring being adapted to grip a screen. 1 9 between itself and one flange of the 'angle' '2. A screen guide comprising an-angl'e; bar, a bow spring secured at one endito said; bar, and a bracket carriedhby 'said";bar" f against which.,the free end of said spril g,"

is constructed tobear, the middle; portionj of said spring being disposed parallelflwith one flange of said. anglebar and fal'franged to frictionallv grip a screen-bet ""t f and such flange.- Y e and side members, and made up of relatively 18 having overlapping ends, and the bottomsbeing further provided with raised portions at least equal in height to the combined 5 thickness of said overlapped ends.

0. A screen guide con'iprising a bottom and side members, sald bottom being made up of alternate elevated and depressed portions, the depressed portions having open 10 ings therethrough,

and fastening devices passing through said openings, the heads of such fastening devices being no. higher than the plane of said elevated portions.

6. A screen guide comprising an angle bar 15-, and a retaining member secured thereto, one

flange of the angle bar being smooth, and the other being made up of alternate elevated and depressed portions, a straight rib 0r bead extending along said last men- !0' 'tioned flange adjacent one edge thereof and adapted to lie flush against a window frame so as to close the openings which would otherwise be produced by said elevated portions.

7.. A screen guide comprising an angle bar .having one flange adapted to be secured to and having the other a Window frame, flange extended beyond the first and bent back upon itself at a distance therefrom,-so as to form a pocket at the into which a screen may tit.

8. In combination, a screen guide having at the lower end thereof a socket adapted to receive the screen, and means for locking the screen in said socket, such means-comprisend of the guide ing a pin extending transversely of the I guide and screen, and a resilient strip mounted on the guide and carrying said pin.

. In testimony whereof I have afiixed my 'slgnature, in presence 'of two. witnesses.
